西旁景教遗址土的工程特性

Engineering Properties of Soil of the Xipang Nestorianism Site in Turfan

位于吐鲁番市葡萄沟内、火焰山西侧小山丘上的西旁景教遗址,在自然和人为的作用下,塌毁严重,对其保护刻不容缓。通过试验得出遗址土含盐量较高,pH值范围在8.4～9.0之间,具碱性,盐分含量与土体中水分富集和迁移关系密切;遗址土粉粒含量普遍在50%左右,砂、砾含量较高,级配不良;遗址土体在干燥状态时强度较高,抗水性弱,遇水易崩解。试验结果为遗址病害调查和保护方案提供了必要的依据。

The Xipang Nestorianism site lied on the hill of the Flaming Mountains in Turfan region is seri?ously damaged under the action of nature and man.So it’s urgently needed to rescue and protect the Xi?pang nestorianism site.Through experimental study we found that the salt content of soil is relatively high with pH range 8.4~9.0.Salt content is closely related to water enrichment and water migration in soil.By analyzing the sieve analysis test data,we found that the gradation of sites soil was bad and its silt content of the sites soil is about 50%and the gravel and sand content is high.The ancient relics soil have good strength in dry condition and are apt to fracturing,Which are useful for the design of protecting and strengthening the ancient city.
